Abstract

As a research for treatment of waste water from acetaldehyde plant by biological method, we investigated general characteristics of the waste water, and isolated and identified some useful bacteria which effectively treated its waste water. Among the total number of 53 strains which were grown in waste water from an acetaldehyde plant, the strains AW-6, AW-22, AW-38 and AW-41 were found to be useful for COD removal of waste water. $COD_{Mn}$ and $BOD_{5}$ of the waste water were 5260 ppm and 6452 ppm, respectively, and pH was 1.85. And the main organic component in waste water was acetic acid which was contained 6.76%. By the taxonomical characteristics, the strains AW-6, AW-22, AW-38 and AW-41 were identified as Micrococcus roseus, Micrococcus luteus, Microbacterium lacticum and Microbacterium laevanifromans or similar strain, respectively.

아세트알데히드 페수를 생물학적으로 처리할 목적으로 폐수의 성상을 조사하였으며, 아세트알데히드 폐수에서 잘 생육하는 53개 균주를 분리 고정하고 그 중 가장 COD 제거율이 우수한 4개 균주 AW-6, AW-22, AW-38, AW-41을 선별하고 이들을 동정하였다. 아세트알데히드 폐수의 성상은 CODmn 5,260ppm, BODs 6,452ppm, pH 1.85였으며 유기성분의 주체는 초산으로 6.76%를 함유하였다. 균의 동정 결과, AW-6은 Micrococcus 갠뎐, AW-22는 Micrococcus luteus, AW-38은 Microbacterium lacticum, AW-41은 Microbacterium laevaniformans 또는 그 우연균으로 동정되었다.
